Thank you, Tim, and good morning, everyone. On Slide 6, our second quarter consolidated gross profit dollars increased by $3.2 million or 8.1%, and our gross profit margin improved 270 basis points to 28.9%. Our gross profit increase was driven by pricing gains over inflation of $2.7 million as well as productivity improvements in our manufacturing facilities of $1.6 million. We also had lower product liability costs of $900,000 compared to a year ago. In addition, the South African subsidiary we acquired last December also added additional gross profit of $400,000. Finally, foreign currency translation had a $2.1 million negative impact on gross margin this quarter.
On Slide 7, selling expense increased 6% from the prior year in dollar terms and represented 11.2% of sales this year compared to 10.3% last year. The increase in selling cost is primarily related to the new sales offices that we've established in Turkey, North Africa and the United Arab Emirates, as well as the incremental selling cost from the South African acquisition we acquired last December. In addition, foreign currency translation had a favorable impact on selling expense of $1.1 million this quarter. G&A expense increased $1.6 million compared with the prior-year, representing 8.6% of sales versus 7.3% in the prior year. While $300,000 of the increase was related to our ERP system implementation, other increases were due to benefit-related items such as pension, group health costs and relocation costs, which together totaled $700,000. Of the $1.6 million increase, approximately $700,000 of the increase was for non-recurring items. We expect our SG&A run rate to be approximately $30 million per quarter.
Turning to Slide 8, operating income increased by 4.9% to $12.9 million or 8.8% of sales compared to 8.2% of sales in the previous year. The improvement in operating income is being driven by the net pricing gains over materials' inflation as well as the continued improvement in operating efficiencies previously discussed.
As you can see on Slide 9, income per diluted share for the second quarter of fiscal 2013 was $0.42, reflecting an $0.08 increase from the prior-year period where we reported earnings of $0.34 per share. The effective tax rate in the quarter was 15.6% versus 31.5% in the prior-year period due to the mix of earnings in the U.S. versus our foreign affiliates and the fact that we have a valuation allowance against our deferred tax assets in the U.S. On a pro forma basis, at a 38% tax rate and excluding income from discontinued operations that we had in the previous year, earnings per share in the second quarter of fiscal '13 were $0.31 per share versus $0.29 per share in the second quarter of fiscal 2012. Our expected effective tax rate for fiscal 2013 is expected to be between 15% and 20%, based on the geographic mix of earnings that we anticipate.
On Slide 10, we have compared our year-to-date performance for several key metrics. Year-to-date, revenue is up 3.4% largely driven by volume and price increases, offset by $14.4 million of unfavorable foreign currency translation. Gross profit is up 15.2%, and gross profit margin has expanded 290 basis points to 28.8%. Higher volumes and net pricing over material inflation, along with manufacturing efficiencies, drove the margin expansion. Year-to-date operating income is up 31.6% as a result of the additional gross margin, despite higher SG&A costs. Operating leverage for the first 6 months of the year is a strong 62.6%. Finally, year-to-date earnings per share is $0.85 per share versus $0.48 in the previous year.
Turning to Slide 11, our working capital as a percent of sales increased to 19.4% in the current quarter from 17.6% in March 31, 2012. This increase is largely driven by lower accounts payable balances and the payment of certain liabilities that were accrued as of our fiscal year-end. As a percent of sales, these 2 items negatively impacted this metric by 2.1%. Inventory turns of 3.7x were lower than the most recent fiscal year-end level of 4.3x due to higher inventory levels associated with projects that we expect to ship this quarter, as well as softer sales volumes in the quarter. We do expect to improve inventory turns by year end and expect to achieve inventory turns of at least 4x.
On Slide 12, you can see we generated $3.5 million of operating free cash flow in the second quarter of fiscal 2013. Capital expenditures were $4.1 million versus $7.2 million in the previous year. We expect the capital expenditures for fiscal 2013 to be in the range of $12 million to $15 million.
Finally, on Slide 13, you can see that as of September 30, 2012, net debt was $57.6 million, and total gross debt was $152.5 million. Net debt to net total capitalization was 24.6%, which is lower than our 30% net debt to net total capitalization ratio goal. In addition to having $94.9 million of cash in our balance sheet at September 30, we have an additional $72.6 million available under our previous $85 million senior credit facility, which is net of $12.4 million of outstanding letters of credit. With the new $100 million 5-year senior credit facility, which was closed on October 19 and replaces the previous $85 million senior credit facility, we have added an additional $15 million of borrowing capacity. In addition, the new facility provides more flexibility and improved pricing. This new facility, along with our healthy cash balance, provides significant liquidity to support our strategic growth plan.
With that, I will turn it back over to Tim to cover the fiscal third quarter outlook.
